Description

garlic harvester

The present invention relates to an agricultural machine, in particular to a garlic harvester suitable for harvesting garlic.

In the past, the garlic (bulb) was harvested mainly by manually digging out the whole garlic plant from the garlic field, and after cutting off the leaf sheath (pseudostem) and root hairs of the garlic plant, the garlic could be obtained, but all the garlic was harvested manually. It is quite time-consuming and labor-intensive to implement, and it is not economical.

For this reason, a variety of mechanized garlic harvesters have been developed on the market at present. Some garlic harvesters are cultivators equipped with coulters. The process with these roots still needs to utilize manpower to carry out. And some garlic harvesters, although they can shovel out the garlic plant and automatically cut off the leaf sheath, do not have the design to remove the roots, so these roots still need to be manually cut off. Therefore existing garlic harvester fails to fully automate operations, and the design still needs to be improved.

Therefore, the purpose of the present invention is to provide a garlic harvester that can at least overcome the shortcomings of the prior art.

Thus, the novel garlic harvester includes a harvesting device, a conveying device, a root removal device, and a stem cutting device. The harvesting device is suitable for shoveling and harvesting a garlic plant.
